Navigation Without Screens

# Localization note — map systems and navigation references vary by country
- Magnetic declination varies significantly by location. Agent must look up
  current declination for the user's area (NOAA for US, BGS for UK, etc.)
  and include it in compass instructions.
- Map systems differ:
  US: USGS topographic maps (7.5-minute quadrangles)
  UK: Ordnance Survey (OS) maps — 1:25,000 Explorer or 1:50,000 Landranger
  France: IGN maps
  Australia: Geoscience Australia topographic maps
  Canada: NRCan topographic maps
- Grid reference systems differ (UTM, MGRS, OS grid references, etc.)
  Adapt grid reading instructions to the local standard.
- Contour intervals vary by map series. Always check the legend.
- Star navigation: Polaris works only in the Northern Hemisphere.
  Southern Hemisphere: use the Southern Cross method instead.
- Emergency numbers: US 911, UK 999, AU 000, EU 112
- Trail marking systems vary (US blazes, European GR system, etc.)

MAP ANATOMY — WHAT YOU'RE LOOKING AT:

LEGEND/KEY (usually bottom or side margin):
- Every symbol on the map is explained here. Read it first.
- Common symbols: blue = water, green = vegetation, brown = contour
  lines, black = human-made features, red/pink = roads
- Symbols vary between map series. Never assume.

SCALE:
- Tells you the ratio of map distance to real distance.
- 1:24,000 means 1 inch on the map = 24,000 inches (2,000 feet)
  in the real world. This is the standard USGS topo scale.
- 1:25,000 (OS Explorer maps, UK): 4 cm on map = 1 km real
- Rule of thumb for 1:24,000: about 2.5 inches = 1 mile
- Use the scale bar printed on the map margin for quick measurement.
  Lay a straight edge (twig, paper strip) along your route, then
  compare to the scale bar.

CONTOUR LINES (the brown squiggly lines):
- Each line connects points of equal elevation.
- Contour interval: the elevation difference between adjacent lines.
  Check the map margin — it's always stated there.
  Common: 40 feet (USGS) or 10 meters (metric maps).
- Lines close together = steep terrain
- Lines far apart = gentle slope or flat
- Concentric circles = hilltop or peak
- V-shapes pointing uphill = valleys/drainages
- V-shapes pointing downhill = ridges/spurs
- Depression: circles with tick marks pointing inward

GRID REFERENCES (locating a specific point):
- Most topo maps have a grid overlay.
- US: UTM grid (easting first, then northing — "read right, then up")
- UK: OS grid references — two letters plus 6 or 8 digits
- To give a 6-figure grid reference:
  1. Read the easting (horizontal) line to the LEFT of your point
  2. Estimate tenths across to your point
  3. Read the northing (vertical) line BELOW your point
  4. Estimate tenths up to your point
  5. Combine: easting digits first, then northing digits

ORIENTING THE MAP:
1. Find a known feature (road, river, building) on both the map
   and in the landscape.
2. Rotate the map until that feature lines up with reality.
3. The map is now oriented — everything else on it should match
   what you see around you.

COMPASS PARTS (baseplate compass — the standard type):
- Magnetic needle: red end points to magnetic north
- Housing/bezel: rotating ring with degree markings (0-360)
- Direction-of-travel arrow: printed on the baseplate, points away
  from you when holding the compass flat in front of you
- Orienting arrow: printed inside the housing, lined up by rotating
  the bezel
- Orienting lines: parallel lines inside the housing

THE BIG THING TO UNDERSTAND — DECLINATION:
- The compass needle points to magnetic north, not true north.
- The difference is called declination and it varies by location.
  US East Coast: ~10-15 degrees west
  US West Coast: ~14-18 degrees east
  UK: ~1-2 degrees west (currently decreasing)
- If you ignore declination on a long hike, you can end up miles
  off course.
- Set your compass for declination ONCE using the adjustment screw
  (if your compass has one) and forget about it.
  Cost of a decent compass: $15-$40. Suunto A-10 or Silva Starter
  are solid entry-level choices.

TAKING A BEARING FROM THE MAP:
1. Place the compass on the map with the edge along your desired
   travel line (from point A to point B).
2. Make sure the direction-of-travel arrow points from A toward B.
3. Rotate the bezel until the orienting lines are parallel to the
   map's north-south grid lines, with the orienting arrow pointing
   to north on the map.
4. Read the bearing at the index line. That's your bearing.
5. Adjust for declination if your compass doesn't have a built-in
   adjustment.

FOLLOWING A BEARING IN THE FIELD:
1. Hold the compass flat in front of you at waist height.
2. Turn your entire body (not just the compass) until the red
   needle sits inside the orienting arrow ("red in the shed").
3. Look up and pick a landmark in the distance along the
   direction-of-travel arrow — a tree, rock, post, whatever.
4. Walk to that landmark. Repeat.
5. Don't stare at the compass while walking. Sight a target,
   walk to it, then re-sight.

COMMON MISTAKE: Holding the compass tilted. Keep it level or the
needle drags on the housing and gives false readings.

TERRAIN ASSOCIATION (navigating by what you see):
1. Before you start walking, study the map. Identify features
   you'll encounter along your route: rivers, ridges, road
   crossings, clearings, changes in vegetation.
2. Create a mental sequence: "First I'll cross a stream, then
   go uphill, then I'll hit a trail junction."
3. As you walk, check off each feature. If you expect a stream
   and don't hit one, stop and reassess.
4. Use "handrails" — linear features (trails, rivers, ridges,
   fences) that run roughly parallel to your direction of travel.
   Follow them and you can't get lost sideways.
5. Use "backstops" — features that tell you you've gone too far.
   "If I hit the highway, I've overshot the campsite."

ESTIMATING DISTANCE ON FOOT:
- Average walking pace on flat ground: ~2.5 mph / 4 km/h
- Add 30 minutes per 1,000 feet (300m) of elevation gain
  (Naismith's Rule — developed in 1892, still accurate)
- Count paces: walk 100 meters on flat ground and count your
  double-steps (every time your left foot hits). Most people:
  60-70 double-paces per 100m. Now you can measure distance
  while walking.

NAVIGATING IN A CITY WITHOUT GPS:
- Cardinal directions: in many US cities, numbered streets run
  one direction, named streets run the other.
- Sun position: rises east, sets west, south at midday (Northern
  Hemisphere). Enough to keep your bearings.
- Satellite dishes point south (in Northern Hemisphere) toward
  the equator — useful quick compass.
- Ask someone. This is an underrated navigation technology.

GIVING CLEAR VERBAL DIRECTIONS:
- Use cardinal directions, not left/right (which depend on which
  way someone is facing).
- Reference permanent landmarks, not temporary ones ("the church"
  not "the blue car").
- Include distance estimates and a "you've gone too far" marker.
- Example: "Head north on Main Street for about three blocks. Turn
  east on Oak — there's a bank on the corner. If you hit the
  railroad tracks, you went one block too far."

THE STOP PROTOCOL:

S — SIT DOWN
    Do not keep walking. Most people who die lost in the wilderness
    do so because they kept moving, made bad decisions from panic,
    and got further from where anyone would look for them.

T — THINK
    When did you last know where you were? What have you done since?
    How long have you been walking? What direction? Can you retrace?

O — OBSERVE
    Look around. Any landmarks you recognize? Can you hear a road,
    river, or other people? Can you see higher ground to get a view?
    Check your map if you have one.

P — PLAN
    Make a deliberate plan. Options:
    1. Retrace your steps to the last known point (usually best).
    2. If you can identify your location on the map, navigate from
       there.
    3. If truly lost and people know your planned route, STAY PUT.
       Make yourself visible and audible. Three of anything is the
       universal distress signal (three whistle blasts, three fires,
       three rock piles).
    4. If no one knows where you are and you must move, go downhill.
       Downhill leads to water. Water leads to trails. Trails lead
       to people.

SUN NAVIGATION:
- Rises roughly east, sets roughly west (varies by season and latitude).
- At solar noon, the sun is due south (Northern Hemisphere) or
  due north (Southern Hemisphere).
- Shadow stick method:
  1. Place a stick vertically in the ground.
  2. Mark the tip of its shadow with a rock.
  3. Wait 15-20 minutes.
  4. Mark the new shadow tip.
  5. Draw a line between the two marks. This line runs roughly
     east-west (first mark is west, second is east).
  6. Stand with west on your left and east on your right.
     You're facing roughly north.

STAR NAVIGATION (Northern Hemisphere):
- Find the Big Dipper (Ursa Major).
- The two stars at the end of the "cup" (the pointer stars)
  point toward Polaris, the North Star.
- Polaris sits at the tip of the Little Dipper's handle.
- Polaris is always within 1 degree of true north.
- It's not the brightest star — it's medium brightness.

STAR NAVIGATION (Southern Hemisphere):
- Find the Southern Cross (Crux) — four bright stars in a cross.
- Extend the long axis of the cross 4.5 times its length.
- That point in the sky is roughly the South Celestial Pole.
- Drop a line straight down to the horizon. That's south.

OTHER NATURAL INDICATORS (useful but less reliable):
- Moss: grows on the shadier, moister side of trees (NOT always
  north — depends on local moisture and sunlight patterns).
  Use as a general tendency, not a compass.
- Prevailing wind: if you know local wind patterns, bent trees
  indicate the general downwind direction.
- Snow melt: snow melts faster on south-facing slopes (Northern
  Hemisphere) due to more sun exposure.

NAVIGATION PRACTICE ROUTES (pick your level):

BEGINNER — Urban/suburban (1-2 hours):
1. Print a paper map of your neighborhood (OpenStreetMap works).
2. Pick a destination 1-2 miles away that you usually drive to.
3. Navigate there on foot using only the paper map.
4. Give yourself verbal directions as you go.
5. Note landmarks along the route you'd never noticed by car.

INTERMEDIATE — Park or trail (half day):
1. Get a topographic map of a local park or trail system.
2. Before you start, orient the map and identify 3 features
   you should encounter.
3. Navigate using the map and terrain association only.
   Keep your phone in your pocket (but ON, for safety).
4. Practice taking a bearing with a compass and following it
   for 200 meters, then checking your position.
5. Practice giving a grid reference for your location.

ADVANCED — Off-trail navigation (full day, with a partner):
1. Pick two points on a topo map connected by no trail.
2. Plan a route using terrain features (follow the ridgeline,
   cross at the stream junction, climb to the saddle).
3. Navigate using map and compass only. No GPS.
4. Track your pace count to estimate distance traveled.
5. Identify your position on the map at least every 30 minutes.

CRITICAL: Always tell someone where you're going and when
you expect to be back, even for practice. Carry a charged
phone for emergencies even if you're not using it to navigate.
